Product details

The Siemens SIRIUS 3RV1011-0BA20 is a motor protection circuit breaker sized for a 0.06 kW motor at 400 V AC, with a continuous current rating of 0.2 A and a CLASS 10 trip characteristic. It delivers 100 kA breaking capacity across 240 V through 690 V AC, so it can interrupt high fault currents without upstream coordination concerns in most industrial panels. Phase failure detection is built in, and the main circuit connects via spring-loaded terminals accepting 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with ferrule.

The 45 mm width and 90 mm height fit standard panel layouts;

Frequently asked questions

Where can I buy 3RV1011-0BA20 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing.

What is 3RV1011-0BA20's listed depth?

The depth is 81 mm, which fits standard 35 mm DIN rail enclosures with typical clearance.

What wire sizes does the spring-loaded terminal accept?

The main circuit terminals accept 2x (0.25... 2.5 mm²) solid or 2x (0.25... 1.5 mm²) finely stranded with core end processing. AWG equivalents are 2x (24... 14).

Will 3RV1011-0BA20 drop into a panel specified around 3RV1011-0GA10 without rewiring?

Both share the same 45 mm width, 90 mm height, and DIN rail mounting, so the physical fit is identical. The 0BA20 is rated 0.2 A continuous versus the 0GA10's higher rating — verify the motor FLA matches before swapping; the terminal type and wiring capacity are the same spring-loaded design.
